Physical Setting/Chemistry and Physical Science: Chemistry
The new Regents Examination in Physical Science: Chemistry was first given in June 2026. Physical Setting/Chemistry is given for the last time in June 2027, so both appear on the 2027 schedules.

The required Investigations
What the new exam looks like
45 to 55 one-credit questions in 9 to 11 clusters, each built on a phenomenon.
About 60% multiple choice and 40% constructed response.
Six topics, from Structures and Properties of Matter to Engineering, Technology, and the Applications of Science.
Which exam is yours
Your school enters you for one exam. This course is built for Physical Science: Chemistry; if your class followed the older course and you are entered for Physical Setting/Chemistry, check with your teacher.

A plant makes sulfur trioxide: 2SO2(g) + O2(g) <=> 2SO3(g). The table gives the percent of SO2 converted to SO3 at equilibrium at four temperatures (an invented data set), all at the same pressure. An engineer proposes running the reactor at 400 degrees Celsius instead of 500. Which statement best evaluates the proposal?
Question 2
Mass of sodium-24 in the sample after delivery

A research lab records the mass of sodium-24 left in a sample at times after the sample is delivered (table). Sodium-24 (atomic number 11) decays by beta emission. The sample was made 45.0 hours before it was delivered. What mass of sodium-24 did it hold when it was made, and which nucleus does each decay produce?
